Thierry Zamofing 20c6d690e8 enhance syncronization -> parameters in setup_sync 
-> sp.setup_sync(verbose=args.verbose&0x40,timeOfs=0.03,timeCor=0.0005)
- cleanup code
- add motion markers
- add debug data
- rework triggerSync
- BUT nothing should change in Sync

TODO 5.1.18
-----------
```
Fwd/inv kinematic is not yet fully correct for PVT moves:
Inverse kinematic need to calculate velocities:
Now a simplified approach with no dependencies is implemented:
vqCX=vDX
vqCZ=vDZ
vqW=vW
vqFY=vY
To see the differences compare:
hs.gen_prog(fnPrg='/tmp/prg.cfg',host='MOTTEST-CPPM-CRM0485',mode=1,cntHor=1,cntVert=5,wRng=(120000,120000),pt2pt_time=100)
hs.gen_prog(fnPrg='/tmp/prg.cfg',host='MOTTEST-CPPM-CRM0485',mode=1,cntHor=1,cntVert=5,wRng=(120000,120000),pt2pt_time=100,smt=0)
hs.gen_prog(fnPrg='/tmp/prg.cfg',host='MOTTEST-CPPM-CRM0485',mode=1,cntHor=1,cntVert=5,wRng=(0,360000))
hs.gen_prog(fnPrg='/tmp/prg.cfg',host='MOTTEST-CPPM-CRM0485',mode=1,cntHor=1,cntVert=5,wRng=(0,360000),smt=0)
When using segmented mode (SegMoveTime>0) the velocities are not needed.
With SegMoveTime=0 these velocities are needed and will result in a non optimal trajectory (with the current buggy calculation).

```

rsync -va ~/Documents/prj/SwissFEL/PBTools/pbtools/gather/gather_server root@$PPMAC:/tmp/

ssh -L 10001:localhost:22 root@$PPMAC 'uname -a'
ssh -L 10002:localhost:2332 root@$PPMAC 'uname -a'
-> this tunnels port 22 and 2332 of $PPMAC to 10001 and 10002 of localhost
Tests:
nc localhost 10001
nc localhost 10002

They are just using the new alphy driver. That should have no impact on the motion config.

Current (old) Synchronization
-----------------------------
```
default:
/ESB_MX/src/triggerSync/triggerSync.c -> read usage
simulate start trigger -> pshm->Coord[1].Q[10]=1 to simulate a Jungfrau aquire start\n\
simulate frame trigger -> pshm->Coord[1].Q[11]
Coord[1].Q[0] is incremented at each trigger
Coord[1].DesTimeBase is adjusted at each frame trigger
Coord[1].pDesTimeBase=Coord[1].DesTimeBase.a
gpascii: set Gather.Enable=1
PMAC: LD_LIBRARY_PATH=/opt/ppmac/libppmac/ /tmp/triggerSync 10 0 11 -> wait for start trigger
gpascii: set Start trigger: pshm->Coord[1].Q[10]=1 or set EVR that generates the trigger
PMAC: start Gather (Gather.Enable=2)
count and sync frames:
Coord[1].Q[0] = frame counter
gpascii: stop Gather -> Gather.Enable=0
PMAC: triggerSync stops when Gather.Enable=0
```
Enhanced Synchronization
------------------------
```
(to be tested)
Coord[1].pDesTimeBase=Coord[1].DesTimeBase.a
For “external time base”, in which the coordinate system’s time base value is proportional to the
frequency of an incoming encoder signal or pulse train, Coord[x].pDesTimeBase should be set
to EncTable[i].DeltaPos.a
Setup EncTable:
EncTable[n].type = (3)Software 1/T encoder extension (5)Four-byte read 32 bit int (11) Float 32f or 64f
The ERV are mapped to
//Power PMAC Software Reference Manual.pdf Gate3[i].Chan[j].Status -> page 919 UserFlag
(gate3_1->Chan[0].Status&0x800) = Gate3[1].Chan[0].UserFlag Trigger start
(gate3_1->Chan[1].Status&0x800) = Gate3[1].Chan[1].UserFlag Trigger frame
Use EncTable 20 as Frame counter
Gate3[1].Chan[1].EncCtrl = $encctrl
EncTable[20].type = 3
EncTable[20].pEnc = Gate3[1].Chan[1].UserFlag.a (is same as Gate3[1].Chan[1].Status) thus it will not work
EncTable[20].pEnc1 = Gate3[1].Chan[0].TimerA.a
EncTable[20].index1 = 0
EncTable[20].index2 = 0
EncTable[20].index3 = 0
EncTable[20].index4 = 0
EncTable[20].index5 = 0
EncTable[20].ScaleFactor = 1/256
-> THIS DOES NOT WORK WITH CURRENT CONNECTIONS !
-> ONE PHYSICAL ENCODER WOULD NEED PULSE AND DIRECTION INPUT AND SET Gate3[1].Chan[1].EncCtrl TO 'pulse and direction' mode
> Sys.Ddata[0]=Sys.Ddata[0]+10
Use EncTable 20 as Frame counter
Gate3[1].Chan[1].EncCtrl = $encctrl
EncTable[20].type = 11 //loating point read
EncTable[20].pEnc = Sys.Ddata[0].a
EncTable[20].pEnc1 = Gate3[1].Chan[0].TimerA.a
EncTable[20].index1 = 0
EncTable[20].index2 = 0
EncTable[20].index3 = 0
EncTable[20].index4 = 0
EncTable[20].index5 = 99 //multiply with 100
EncTable[20].index5 = 1 //float64
EncTable[20].ScaleFactor = 1/256
EncTable[20].ScaleFactor=1E-3
Use EncTable 20 as Frame counter
EncTable[20].type = 1 //32 Bit uint
EncTable[20].pEnc = Sys.Udata[0].a
EncTable[20].index1 = 0
EncTable[20].index2 = 0
